War of 1812, (June 18, 1812–February 17, 1815), conflict fought between the United States and Great Britain over British violations of U.S. maritime rights. It ended with the exchange of ratifications of the Treaty of Ghent.

The tensions that caused the War of 1812 arose from the French revolutionary (1792–99) and Napoleonic Wars (1799–1815). During this nearly constant conflict between France and Britain, American interests were injured by each of the two countries’ endeavours to block the United States from trading with the other.

American shipping initially prospered from trade with the French and Spanish empires, although the British countered the U.S. claim that “free ships make free goods” with the belated enforcement of the so-called Rule of 1756 (trade not permitted in peacetime would not be allowed in wartime). The Royal Navy did enforce the act from 1793 to 1794, especially in the Caribbean Sea, before the signing of the Jay Treaty (November 19, 1794). Under the primary terms of the treaty, American maritime commerce was given trading privileges in England and the British East Indies, Britain agreed to evacuate forts still held in the Northwest Territory by June 1, 1796, and the Mississippi River was declared freely open to both countries. Although the treaty was ratified by both countries, it was highly unpopular in the United States and was one of the rallying points used by the pro-French Republicans, led by Thomas Jefferson and James Madison, Inwresting power from the pro-British Federalists, led by George Washington and John Adams.  

After Jefferson became president in 1801, relations with Britain slowly deteriorated, and systematic enforcement of the Rule of 1756 resumed after 1805. Compounding this troubling development, the decisive British naval victory at the Battle of Trafalgar (October 21, 1805) and efforts by the British to blockade French ports prompted the French emperor, Napoleon, to cut off Britain from European and American trade. The Berlin Decree (November 21, 1806) established Napoleon’s Continental System, which impinged on U.S. neutral rights by designating ships that visited British ports as enemy vessels. The British responded with Orders in Council (November 11, 1807) that required neutral ships to obtain licenses at English ports before trading with France or French colonies. In turn, France announced the Milan Decree (December 17, 1807), which strengthened the Berlin Decree by authorizing the capture of any neutral vessel that had submitted to search by the British. Consequently, American ships that obeyed Britain faced capture by the French in European ports, and if they complied with Napoleon’s Continental System, they could fall prey to the Royal Navy.

when world war i broke out across europe in 1914, president woodrow wilson proclaimed the united states would remain neutral, and many americans supported this policy of nonintervention. however, public opinion about neutrality started to change after the sinking of the british ocean liner lusitania by a german u-boat in 1915; almost 2,000 people perished, including 128 americans. along with news of the zimmerman telegram threatening an alliance between germany and mexico, wilson asked congress for a declaration of war against germany. the u.s. officially entered the conflict on april 6, 1917.
